The Hudson–Fulton Celebration from September 25 to October 9, 1909 in New York and New Jersey was an elaborate commemoration of the 300th anniversary of Henry Hudson’s discovery of the Hudson River and the 100th anniversary of Robert Fulton's first successful commercial application of the paddle steamer. The maritime achievements of Hudson and Fulton foreshadowed the importance of the river to New York's progress and identity. Organizers used the event not only to display the success of the two men, but also the status of New York City as a world city and the achievements of its citizens.

Robert Fulton was an American engineer and inventor who is widely credited with developing the world's first commercially successful steamboat, the North River Steamboat. In 1807, that steamboat traveled on the Hudson River with passengers from New York City to Albany and back again, a round trip of 300 nautical miles, in 62 hours. The success of his steamboat changed river traffic and trade on major American rivers.
